Abstract
An air conditioner for automotive vehicles is disclosed. The flow rates of air supplied to an evaporator () and a heater () are adjusted by rotationally displacing a scroll casing () and thus changing an air flow from a blower () to a predetermined direction. The air-mix door can thus be eliminated to allow a smaller size of an air-conditioner casing () (air-conditioning unit ()). Also, the ratio between cool air flow rate and hot air flow rate is adjusted by rotationally displacing the scroll casing () with a spur gear () and, therefore, the size and the production cost of the air conditioner can be reduced as compared with a conventional system in which an air-mix door is swung by a link mechanism.
